To know what you should feed your BP at this time it's easy forget the scale forget the weight of the snake and prey feed a prey that is equal to the girth size of your snake (widest part of your BP's body)

Once your BP is an adult it will be different if you want an animal that feed with consistency feed smaller preys (55/75 grams rats to males and 85/120 grams rats to females) which we are obviously far from the 10% to 15% that some may suggest.
